Average velocity of object

  1. Aug 26, 2007 #1
    1. The problem statement, all variables and given/known data
    An object starts from rest at the origin and moves along the x axis with a constant
    acceleration of 4m/s^2. Its average velocity as it goes from x=2m to x=8m is?

    2. Relevant equations
    I think V=bt^2. But not quite sure.

    3. The attempt at a solution

    No idea, how to solve.

    find the general formula for average velocity.
    and, find "t", using the given data, and one of those uniform acceleration equations

    How do you find "t" using average velocity?

    d= d0 + v0t+0.5gt^2 equation
